, whereas tropical astrology ignores precession. This has caused the two systems, which were aligned around 2,000 years ago, to drift apart over the centuries. Ayanamsa systems used in Hindu astrology (also known as Vedic astrology) include the Lahiriayanamsa and the Raman ayanamsa. The Fagan-Bradley ayanamsa is an example of an ayanamsa system used in Western sidereal astrology. As of 2020, sun signs calculated using the Sri Yukteswar ayanamsa were around 23 degrees behind tropical sun signs. Per these calculations, persons born between March 12 - April 12, for instance, would have the sun sign of Pisces. By contrast, persons born between March 21 - April 19 would have the sun sign of Aries per tropical calculations. Sidereal Units: According to : Small units of time used in the Vedas:

(gods), Manus (progenitors of mankind), and Brahma (creator god). The division of a year for each is twelve 30-day months or 360 days, where a day is divided into a 12-hour day proper and 12-hour night. A 30-day month amounts to four 7-day weeks with an extra 8th day every two weeks (48-week year). A traditional human year is measured by the sun's northern ('' uttarayana'') and southern ('' dakshinayana'') movements in the sky, where the new year commences only when the sun returns to the same starting point and a pause on the commencement otherwise. Ebenezer Burgess postulates an intercalary month was inserted every five years to anciently maintain the correspondence of the 360-day years with the true solar years (~365.24-day years). For this reason, a traditional 360-day year is equivalent to a modern ~365.24-day solar or tropical year.


Cosmic date

According to Puranic sources, Krishna's departure marks the end of the human age of '' Dvapara-yuga'' and the start of '' Kali-yuga'', which is dated to midnight on 17/18 February 3102 BCE of the proleptic Julian calendar. We are currently halfway through Brahma's life (''maha-kalpa''), whose lifespan is equal to the duration of the manifested material elements, from which Brahma manifests his universe in '' kalpa'' cycles: * 51st year of 100 (2nd half or ''parardha'') * 1st month of 12 * 1st '' kalpa'' (''Shveta-Varaha Kalpa'') of 30 * 7th '' manvantara'' ( Vaivasvatha Manu) of 14 * 28th '' chatur-yuga'' of 71 * 4th ''

specify that the start and end of each of the ''yugas'' are marked by astronomical alignments. This cycle's '' Treta-yuga'' began with 5 planets residing in the "Aries" constellation. This cycle's '' Dvapara-yuga'' ended with the "Saptarshi" constellation (Ursa major) residing in the "Magha" constellation. The current '' Kali-yuga'' will end with the Sun, Moon and Jupiter residing in the "Pushya" sector.

At the start of Brahma's days, he is re-born and creates the planets and the first living entities. At the end of his days, he and his creations are unmanifest (partial dissolution).
